Equations for c, i, g, and nx are given below. if the equilibrium level of gdp is $21,500, what is the marginal propensity to consume? c = 1,500 + (mpc)y i = 1,000 g = 2,000 nx = -200 a.0.67 b.0.75 c.0.8 d.0.9

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
